IMPROVEMENT IN FIRE-PLACE RADIATORS.

Specification forming part of Letters Patent No. 156,912, dated November17, 1874; application filed October 1, 1874.

To all whom Iit may concern Be it known that I, CHESTER COMSTOGK, of NewCanaan, in the county of Faireld and State of Connecticut, have inventeda new and Improved Fire-Place Radiator, of which the following is aspecification:

Figure l is a face view of my improved fireplace radiator. Fig. 2 isavertical central section of the same; Fig. 3, a sectional face view ofone of the radiating-chambers; Fig.

4 a longitudinal, and Fig. 5 a transverse, section thereof.

Similar letters of reference indicate corresponding parts in all thefigures.

`The object of this invention is to utilize the fire-places which arebuilt into nearly all dwelling-houses for locating steam or hot-waterradiators.

The invention consists in a steamy-radiator adapted to the recess andconfiguration of an ordinary fireplace. 1

Dwelling-houses that were built in former years were mostly providedWith fire -places for useful purposes, but modern arrangements have madenearly all such Ere-places useless, and they are now constructed morefor the sake of ornament than for actual use. At the same timesteam-radiators are largely employed, and take away valuable space inrooms, besides being frequently of a form not in harmony with thefurniture that may be selected. By adapting a radiator for insertioninto a lire-place, I utilize a space that would otherwise be useless,and at the same time am enabled to make the radiator a constant ornamentof a room, and very effective besides.

In the accompanying drawing, the letter A represents the mantel of thelire-place, iliade in the usual or suitable style, to embrace andembellish a recess, B, within which my improved radiator C is placed.This radiator consists of one or more hollow radiating-chambers, a a,which are connected with the steam or hot-water supply pipe b and witheach other, to insure a proper circulation of steam or hot water throughthem. A sheet-metal casing or curtain, d, may be arranged at the back ofthe radiator proper, for the purpose of preventing the walls of thehouse from becoming overheated, and also for radiating purposes. Theface-plate c of the radiator is shaped to conform to the outline oftherecess in the fire-place, but around the edges of said face-plate e isformed an open space, m, through which the air may enter the recess ofthe fire-place and escape therefrom. The air will thus become heated bycontact with the radiating-surfaces, and circulate, by the con-- Inimitation of the ordinary hearth-piece used in front of grates, I use ahorizontal radiator, D,projecting forward from the main tire-placeradiator C, and containing one or more chambers, f f, for the receptionof the hot water or steam from the pipe b, as clearly indicated in Fig.2. A perforated plate, g, embraces and forms the edge of this horizontalradiator D, and allows the radiated air from D to escape into the room.Thus the coldest air of the room, which is at the bottoni, will bewarmed by the horizontal hearth-radiator D, and ascend from it into theroom, while the topV plate h of such hearth'radiator also serves as adirect radiating-surface.

In Figs. 3, 4, and 5 I have represented detail views of the steam andhot-Water chain bers a or f, which I prefer to use in my radiator. Everysuch chamber I prefer to form of two plates, t' and j, which at theiredges are bent inward, and joined by bolts l passing through them, asclearly shown in Fig. 4. The joint may be made tight by galvanizing theentire chamber, or otherwise.

I claim as my inventionl. A fire-place radiator, C, adapted for insertion into a fire-place, and constructed of one or more chambers, a,of the radiating front plate e, and of the metal curtain d arranged atthe back, all combined substantially as described.

2. In combination with a lire-place radiator, adapted for insertion in aflre-place, and constructed of one or more chambers', and ot' aradiating front plate, the horizontal or hearth radiator D, composed ofthe chamber or chambers f and perforated face-plate g, f'or usesubstantially as specified.
